Odd problem that has started several weeks ago. The TV will turn off for no good reason or warning, or will turn on when it is off. Also the on-screen volume display will come and go. All of this happens with **NO** input from any of the remote controls. The problem is very erratic as to when it happens --- many days not at all, or at different times of the day/nite. I have even removed all the batteries from all the remotes, and this problem has still happened. Someone has suggested that one of my neighbors has a "high powered" remote control that is doing this??? Sure seems like it. But really --- does anyone have any thoughts on this?
